To a/ZZ whom it may concern;

Be it known that I, EDWARD A. Enos,` a citizen of the United States ofAmerica, residing at East Oonnersville, Fayette county, Indiana, haveinvented a new and useful Multiple Brick-Molding Machine, of which thefollowing is a specification.

My invention relates to improvements in brick-molding machines in whichare used two sides with rentrant angles, said sides being each hinged atone end thereof and of such a shape that when closed they formrectangular recesses for the reception of the material from which thebricks are molded. When the sides are swung open, the palletboard withthe bricks thereon can be readily removed. I attain these objects by theapparatus illustratedin the accompanying drawings, in which* Figure 1 isa plan view of the machine with the bars closed and latched ready forthe introduction of the cement or brick` composition. Fig` 2 is a sideview of same in same relative position. Fig. 3 is a top view of palletor mold board after removal from the machine, showing the freshly-moldedbricks in position relative to the peculiar parting of mold side bars atgeometrically opposite corners. Fig. 4 is an end elevation of themachine. Fig. 5 is a plan view, on a smaller scale, showing themold-bars swung outward; and Fig. 6 is a plan view of a part of themachine, showing a modified form thereof.

A represents the bottom board, and B the follow-board, supported byblocks on the board A. On the follow-board B rests the pallet or dryingboard O.

D represents the pivot-pin for the side mold-bars, which is heldl in abase-piece K, which is secured by screws L to the baseboard A. On thispin D are mounted the side mold-bars E and F, each of which'is providedwith a perforated lug engaging said pin. Each of these mold-bars isprovided with a series of rentrant angles, each angle forming two sidesof a mold, the other two sides being formed by a similarly-arrangedangle on the other bar. These angles are so arranged that each bar canbe easily swung outward and not touch the molded articles in its swingand also so that they may be swung clear of the pallet O, permitting theeasy removal of the latter with the molded articles upon it. Thisoperation is clearly shown in Fig. 5, as before stated. The cleviscamlatch G, Fig. 2, is pivotally hung in suitable extensions or lugs atthe extremity of the mold side bar, and upon bringing together the saidmold side bars the link or clevis can be closed over a suitable lug orextension I on lconjugate side bar, and by the manipulation of thecam-ended lever H, leccentrically journaled in the link G, sufficientpressure can be brought upon the extension I to hold the mold side barsrmly together.

Any special surface can be reproducedsuch as rough or stone facedbrick-by properly indenting the inner faces of the mold side bars E andF. Same are, however, shown plain or smooth for the sake of clearness.When the rough or stone face is required on the short side or end ofbrick, means for releasing same in conjunction with theoutwardly-swinging mold side barsHsuch as the supplementary hinged end J(shown in Fig. 6)-is provided.

I claim- 1. In a brick-molding machine, the combination of a base-board,a pivot-pin, side mold-bars each provided with a series of reentrantangles, mounted on said pin, and a latching device, substantially asdescribed.

2. In a brick-molding machine, the combination of a base-board, afollow-board thereon, a pivot-pin secured to said lbase-board, a pair ofside mold-bars, each provided with a perforated lug engaging said pinand each provided with a series of rentrant angles, the angles on onebar being symmetrically disposed in relation to those on the other bar,substantially as described.

3. In a brick-molding machine, the combination of a base-board, apivot-pin mounted thereon, a pair of side mold-bars pivotally mounted onsaid pin, each bar being provided. with a series of rentrant ano-les andone of said bars being provided with an end piece, hinged to the end ofthe last angle, for ready disengagement, substantially as described.
